變(bian)(bian)(bian)壓(ya)(ya)器特(te)別是(shi)(shi)在高溫(wen)下，其老化速(su)度(du)就更快(kuai)，油(you)(you)箱(xiang)(xiang)加工設備，極易引(yin)起(qi)密封(feng)件老化、龜裂(lie)，變(bian)(bian)(bian)質、變(bian)(bian)(bian)形，以(yi)至失效，塑料油(you)(you)箱(xiang)(xiang)加工，造成變(bian)(bian)(bian)壓(ya)(ya)器滲漏油(you)(you)。 對于不(bu)同型(xing)號(hao)和不(bu)同容量的變(bian)(bian)(bian)壓(ya)(ya)器，無論是(shi)(shi)采用法蘭連接還是(shi)(shi)螺紋連接，液壓(ya)(ya)站(zhan)油(you)(you)箱(xiang)(xiang)加工，更換密封(feng)件前必須(xu)先清除連接面上(shang)的塵土和銹跡。變(bian)(bian)(bian)壓(ya)(ya)器油(you)(you)箱(xiang)(xiang)應裝有(you)下列閥門：①變(bian)(bian)(bian)壓(ya)(ya)器主油(you)(you)箱(xiang)(xiang)、儲油(you)(you)柜(ju)的排污(wu)閥；②取(qu)油(you)(you)樣閥（取(qu)油(you)(you)樣閥應具(ju)有(you)8mm以(yi)上(shang)的內(nei)螺紋并配有(you)可取(qu)下的栓塞(sai)）

變(bian)壓(ya)(ya)(ya)器(qi)油箱(xiang)(xiang)外(wai)殼(ke)接(jie)(jie)地(di)對接(jie)(jie)地(di)裝置的(de)要(yao)求：①接(jie)(jie)地(di)體(ti)與接(jie)(jie)地(di)線(xian)應(ying)焊(han)接(jie)(jie)牢固(gu)。②接(jie)(jie)地(di)電(dian)阻應(ying)不大于0.5Ω，地(di)線(xian)與設(she)備(bei)應(ying)可靠連接(jie)(jie)。③圓鋼(gang)接(jie)(jie)地(di)體(ti)直徑應(ying)符合有關規定。油箱(xiang)(xiang)底部兩對角處(chu)應(ying)設(she)有兩塊(kuai)供油箱(xiang)(xiang)接(jie)(jie)地(di)的(de)端(duan)子（變(bian)壓(ya)(ya)(ya)器(qi)油箱(xiang)(xiang)即外(wai)殼(ke)接(jie)(jie)地(di)主要(yao)是為了保障人身(shen)(shen)安全(quan)。當變(bian)壓(ya)(ya)(ya)器(qi)的(de)絕緣損壞時，變(bian)壓(ya)(ya)(ya)器(qi)外(wai)殼(ke)就會帶(dai)電(dian)。變(bian)壓(ya)(ya)(ya)器(qi)油箱(xiang)(xiang)(波紋(wen)油箱(xiang)(xiang))豎直設(she)計是為了使冷卻油依靠自身(shen)(shen)密(mi)度的(de)變(bian)化(由于溫(wen)度變(bian)化導致的(de))形成(cheng)對流，提高(gao)散(san)熱效率。變(bian)壓(ya)(ya)(ya)器(qi)油箱(xiang)(xiang)(波紋(wen)油箱(xiang)(xiang))散(san)熱管(guan)里面要(yao)有冷卻油，是管(guan)道形的(de)。

油(you)(you)(you)箱(xiang)(xiang)底部(bu)兩對角(jiao)處(chu)應設有(you)兩塊供油(you)(you)(you)箱(xiang)(xiang)接地的端子（變(bian)(bian)(bian)(bian)壓(ya)器(qi)(qi)(qi)(qi)(qi)油(you)(you)(you)箱(xiang)(xiang)即外殼接地主要是(shi)(shi)為了(le)保障人身安全(quan)。當變(bian)(bian)(bian)(bian)壓(ya)器(qi)(qi)(qi)(qi)(qi)的絕(jue)緣損(sun)壞時，變(bian)(bian)(bian)(bian)壓(ya)器(qi)(qi)(qi)(qi)(qi)外殼就(jiu)會帶電。變(bian)(bian)(bian)(bian)壓(ya)器(qi)(qi)(qi)(qi)(qi)滲漏(lou)油(you)(you)(you)，橡膠密封(feng)件(jian)失效和焊(han)(han)縫(feng)開(kai)裂 ，變(bian)(bian)(bian)(bian)壓(ya)器(qi)(qi)(qi)(qi)(qi)的焊(han)(han)點多、焊(han)(han)縫(feng)長，而(er)油(you)(you)(you)浸式變(bian)(bian)(bian)(bian)壓(ya)器(qi)(qi)(qi)(qi)(qi)是(shi)(shi)以(yi)鋼(gang)板(ban)焊(han)(han)接殼體為基(ji)礎的多種焊(han)(han)接和連(lian)接的集合體。 一般(ban)大型變(bian)(bian)(bian)(bian)壓(ya)器(qi)(qi)(qi)(qi)(qi)均(jun)采用鐘罩(zhao)式油(you)(you)(you)箱(xiang)(xiang)，鎮江油(you)(you)(you)箱(xiang)(xiang)加工(gong)，這(zhe)種變(bian)(bian)(bian)(bian)壓(ya)器(qi)(qi)(qi)(qi)(qi)的器(qi)(qi)(qi)(qi)(qi)身自重(zhong)(zhong)都在(zai)(zai)200t以(yi)上(shang)(shang)，總重(zhong)(zhong)量均(jun)在(zai)(zai)300t以(yi)上(shang)(shang)，運輸(shu)起來比較困難。當進(jin)行器(qi)(qi)(qi)(qi)(qi)身檢修時，不必吊出(chu)笨重(zhong)(zhong)的器(qi)(qi)(qi)(qi)(qi)身，只(zhi)要吊去(qu)較輕的箱(xiang)(xiang)殼，即可(ke)進(jin)行檢修工(gong)作。
